| Zusammenfassung |
In 1997, reliable operation of the EISCAT
Svalbard Radar (ESR) was achieved and a rocket launching facility at Ny Ålesund
on Svalbard (79°N, 12°E) (SVALRAK) was established. On 20 November, 1977, the
first instrumented payload was launched from SVALRAK. Although the payload
configuration had been flown many times previously from Andøya Rocket Range on
the Norwegian mainland, this presented an unprecedented in situ determination of
positive ion density over Svalbard. Simultaneously, ESR measured similar density
profiles but in a higher altitude regime. We have combined the ESR measurements
with ionosonde data to establish a calibration and subsequently combined the
ground-based and in situ determined profiles to give a composite positive ion
density profile from the mesosphere to the thermosphere.
Key words: Ionosphere (polar ionosphere; instruments
and techniques) |
